The surname McAilin is derived from the personal name Hugelin, which is a diminutive of Hugh. The Gaelic form of the name is Mac Uighilin.

Early Origins of the McAilin family

The surname McAilin was first found in County Antrim (Irish: Aontroim) located in the province of Ulster in present day Northern Ireland, where they were granted lands by Strongbow after the Anglo/Norman invasion of Ireland in 1172.

Specifically, "The MacQuillans were lords of the territory of the Routes, in co. Antrim, holding their chief residence in the fine old sea-girt castle of Dunluce." MacLysaght agrees "The MacQillans are of Norman-Welsh descent: they settled soon after the invasion in the territory called the Route (co. Antrim.)" 1

One of the first records of the family was Malcolm MacQuillan who died in 1307. Little is known of his heritage, but what we do know is that he was granted safe conduct by the English so he could assail Scottish forces, on Scotland's western seaboard, with his galley fleet. He was part of a fleet of eighteen galleys with 1,000 men who landed near Stranraer, now a town in southwest Scotland in Inch, Dumfries and Galloway. But, this force was quickly overwhelmed by local forces led by Dungal MacDouall. MacQuillan was captured and executed. His head and the heads from two Irish chiefs were sent back to King Edward I.

Migration of the McAilin family

In the mid-19th century, Ireland experienced one of the worst periods in its entire history. During this decade in order to ease the pressure of the soil, which was actually depleted by the effects of the previous years' grain crops, landowners forced tenant farmers and peasants onto tiny plots of land that barely provided the basic sustenance a family required. Conditions were worsened, though, by the population of the country, which was growing fast to roughly eight million. So when the Great Potato Famine of the mid-1840s hit, starvation and diseases decimated the population. Thousands of Irish families left the country for British North America and the United States. The new immigrants were often accommodated either in the opening western frontiers or as cheap unskilled labor in the established centers. In early passenger and immigration lists there are many immigrants bearing the name McAilin: Andrew, Charles, James, John, Patrick, William McQuillan arrived in Philadelphia between 1840 and 1860; Edward, George, Patrick, Phillip, Roger and Thomas McQuillen all arrived in Philadelphia between 1840 and 1860.
